This paper demonstrates how the transcendental number "e" may be arrived at by observing the discharge of a capacitor through a fixed resistor and then modelling the system using a simple step-wise procedure. The experimental phase makes use of the Arduino microcontroller, while simple modelling of the system is carried out by means of…

Previous research evaluating grammar school effectiveness has generally relied on snapshot or longitudinal regression models to deal with pre-existing differences between grammar school pupils and those in non-selective schools. These passive designs are based on correlations, and cannot demonstrate clear positive causal relationships between…

This paper reports on findings from an analysis of trait-formation tasks in the genetic sections of high school biology textbooks. Drawing on studies exploring a range of problems in students' explanations of trait formation, we investigated trait-formation tasks and analysed their potential for knowledge integration and multi-level mechanistic…

There is no clear-cut division between orality and literacy (Street, 1993). This idea is central to literacy development in the Spanish heritage language (SHL) context because the opportunities to use heritage language (HL) skills are often oral, not written. Furthermore, the cultural situations that speakers find for their language are less…

For 23 years, the author worked with high school students from a wide range of language backgrounds and widely differing circumstances. What they all had in common was that they were all developing competence and confidence in academic English. One of the challenges in teaching them was that some students had traveled back and forth between the…

With the growing complexity of societal and scientific problems, research centers have emerged to facilitate the conduct of research beyond disciplinary and institutional boundaries. While they have become firmly established in the global university landscape, research centers raise some critical questions for research evaluation. Existing…

Many research problems in social science involve multilevel phenomena. However, discussions about multilevel research designs are limited in the mixed methods (MM) literature. Building on early writings in the field, this methodological discussion advances a refined definition of a multilevel MM research design. The refinement emerges from a…

The growth of the Maker Movement has had a profound impact on museum education, particularly in science centers and museums that have established Maker Spaces, Fab Labs, or Tinkering Studios. While this has resulted in new educational practice taking root in these organizations, it has also raised the question of how best to support museum…

Test, measurement, and evaluation are concepts used in education to explain how the progress of learning and the final learning outcomes of students are assessed. However, the terms are often misused in the field of education, especially in Ghana. The objective of the study was to thoroughly explain the concepts to assist educationists and…

The Programme for the International Assessment of Adult Competencies (PIAAC) assesses key skills in literacy, numeracy and problem-solving in technology-rich environments, as well as their relationship to other social outcomes for adults. PIAAC's developers claimed to better account for adults' literacy practices than earlier international studies…

A common belief is that the Bookmark method is a cognitively simpler standard-setting method than the modified Angoff method. However, a limited amount of research has investigated panelist's ability to perform well the Bookmark method, and whether some of the challenges panelists face with the Angoff method may also be present in the Bookmark…

In this commentary, pedagogical reflection is examined through the lens of a practitioners' personal memories of childhood play. The telling of these stories uncovers and describes the ways in which teachers' personal "play histories" and their reflections upon them could inform their facilitative relationship to, provision for, and…

This article considers the current position of computer-assisted language learning (CALL) research by producing an integrative synthetic overview of all the articles published in three leading international CALL journals: "ReCALL" (in its 31st year of publication), the "CALICO Journal" (its 36th) and "Computer Assisted…

The failure of the news media to include diverse voices is a global issue. Journalism students and novice journalists need to be trained how to report on marginalized communities. However, this training necessitates journalism educators to both recognize why these attempts have failed in the past and be proactive in identifying ways in which…

The World Journalism Education Congress (WJEC) holds global conferences every 3 years offering a unique opportunity for attendees: access to its Syndicate Program. The program gives participants the chance to meet in small groups with international counterparts to take part in research-based discussions focused on the most important journalism…
